I'm going to add a new wrinkle to this "airfare through
ABD or not" discussion. Of course, take this with a grain of salt that these are strange times as far as flights are concerned, and this may not always be an issue. There is currently a discussion going on in a fb group I belong to, because a member of the group found out the night before they left for their ABD that the first leg of their flight was cancelled. They found out because they checked their reservation at 10pm last night. They booked through ABD, but heard nothing from them, because ABD is now closed on the weekends. Apparently United notified ABD of the change at noon yesterday (Saturday), but ABD obviously didn't get it because no-one is there. Both they and their
Travel Agent tried to contact the ABD after-hour phone number, but no-one ever returned the calls. Luckily, United was willing to work directly with them, and they got rescheduled to fly out tomorrow instead of today. Also luckily, they had scheduled a pre-day, so they are only missing that. They get in at like 10am the morning of the first day of the ABD, which is far from ideal, but better than nothing. But if they'd known earlier, perhaps they could have made better arrangements.
So the upshot is a) if you book or have already booked your flights with ABD, you run the risk of missing notifications of flight changes if they happen over the weekend, so keep an eye on your reservation! b) maybe consider booking your airfare yourself for a while until things "normalize" a bit more. And c) try and give yourself extra time if you can to fly anywhere right now. It was the domestic leg that got cancelled!
